Validation of the six potential biomarkers between healthy control (HC) and acute injury (AI) patients by ELISA. The concentrations of CA1 (a), MMP9 (b), QPCT (c), HCAR2 (d), UGCG (e), and LDHB (f) in serum samples from the HC (n = 30) and AI groups (n = 55). The error bars represent means ± SEM. *p < 0.05, **p < 0.01, vs. HC group
